Used this for the first time to stock up on water/drinks and grab & go cereal bars to take to the Disney Parks during our 10 day visit in August. So worth having a case of water ($7 for 36 bottles instead of $2.50 a bottle at the park!) to put in the room fridge. Order delivered to our resort and waiting for us when we checked in. Will definitely use Garden Grocer again.
I wrote a brief review of Garden Grocer here: http://www.lovelogicandlaughter.com/2014/06/disney-tips-and-tricks-disney-world.html
I was extremely pleased with the prompt delivery and friendly employees I dealt with when I called. The groceries were waiting for us when we arrive, just as promised! I will use Garden Grocer for every Disney Trip from now on.
